The Final Formula for the Exact Amount of Fountain pens you need to have.

 

After having worked hours and hours to find that formula, it's now ready for each of you. Perhaps it can help you to explain to your wife or husband how il goes :   

 

n + 1  is the correct formula. N being the number of Fountain pens you already have .....

Yup, that's more or less exactly the formula I'd come up with as well, except mine ran:  

 

Nfp+1= QTY(Optimal)

Funny how we all seem to have come up with the same formula? What are the statistical odds of that!?

You'll still need another condition:

Even up to the point of infinity, the total number of pens you own must still be less than the number where S(H)WMBO would allow you to have, more than which great arguments and/or separation might occur.

My biggest problem is that my wife cannot understand that kind of formula . I think that I should try another way : changing the words"fountain pen" by "pair of shoes" applied to her going shopping ....;-). That should do it .....

While your formula is sound in principle, it neglects opportunities to purchase sets and entire collections. As I would never instruct others to purchase multiple items I will begrudgingly step in to save you from yourself. Sometimes one must accept a responsibility to the group and be willing to sacrifice.

Thank you, Thierry :blush: If I was a mathematician, I would enjoy this even more, but it fits!

Seeing your Sheaffer collection made me think...one can always add another pen box.

Is that supposed to be a threat? Possibly on a piece of paper with a black spot, or in the mouth of the horses head you find on your pillow?

I know what you mean I'm on 13 pens in my collection and I think that 20 will be where I will stop, however when I hit 20 I bet I will be saying 30.

I will probably stop when the number of nice pens I regret not using more because of all the other nice pens I love to use will become intolerable. Sometimes I feel I'm close to that - until the next gotta-have-it-too comes along...

My collection has been determined by (1) What looks good at Dromgoole's that's in my budget and (2) the size of my present pen case. I just got a
bigger pen case!

So, if I apply the Joker4Eva Limit to the Krisbecause Monthly Incremental Theory, I get:

 

OPTQUANTPENS(0)=1

 

OPTQUANTPENS(nextmonth)=OPTQUANTPENS(thismonth)+1-QUANTPENSOWNED/SWMBOLIMIT

 

I think there is some evidence that "dark pens" exist in office desks and in a box at the back of a drawer; these do not interact with SWMBO, and therefore are not subject to the Joker4Eva limit.

Yup.  Except that in my case it was 40 and now roughly 70....

My husband thinks I have too many pens.  I think I have somewhere between "too many" and "not enough"....  :lol: 

But then, I took Art, not Math (oh, and the hubby, with a degree in Applied Mathematics/Computer Science) has more or less stopped saying "Guess how many pens she has" and has instead taken to saying "Guess how many INKS she has"...).  To which, again, I reply "Not nearly enough!" (okay, I have over 100 samples at this point, but a lot of those are inks I didn't really liked.  Or duplicates (please, don't ask me why/how I accidentally ordered three samples of DCSSB instead of just one; just... don't -- it will be better for both of us, really...).  Come to think, I haven't ordered ink for a WHILE now -- and there are several that are "must haves" that I need to get full bottles of....
